We saw the sign for Oak Springs Trilobites a few weeks ago coming back from the Pahranagat NWR and I'd been wanting to make the trip out to try and find some. We took Bean and went out there on Saturday to try our luck. We didn't really have any luck, but we had a really nice drive out in the boonies and ate a picnic there and enjoyed poking around and beating on some slate rocks trying to find some. We did find some pretty dendrites. Here's what they are:
Dendrites in geology are tree-like, branching mineral formations, typically composed of manganese or iron oxides, that grow on rock surfaces or within fractures. Often mistaken for fossils, they are actually inorganic, non-equilibrium crystals that form as rapid, fractal growth patterns when mineral-rich water flows through narrow spaces. They are pretty, and we were glad that we at least found those!
